Hey guys I have been struggling with this for about 4 months and it's so frustrating. It started a month and a half after buying the computer so the 1 month warranty ran out. What happened at first was the PC started rebooting completely randomly even if it was just sitting idle. It was running on Win8 so after I did some research I thought maybe it was the OS so I got rid of the lovely Windows 8 and downgraded to 7. That didn't work. It kept doing the reboots. About a month and a half ago I got fed up and sent the mobo in for RMA. It came back and the reboots continued. It restarted on start up (BIOS screen, Welcome screen, etc.) An idea came to me and I removed one stick of RAM which left only 4GB on the computer. Then it booted up completely. After 30 minutes or so it didn't reboot, it froze. The mouse and keyboard were useless and there were weird small blue lines flickering on the screen. I then had to force reboot. I tried both sticks of memory at a time to see if maybe only one of them was messed up. They both failed the manual test. I also ran Windows Memory Diagnostic but it had no errors. Keep in mind this was the Win7 tool. Today I took the computer to the person who sold it to me, who is also a technician. He took my ram, put it in his windows 8 PC and ran memtest on it. It showed some errors but he said it wasn't crucial. He also said he thought it was the mobo and he explained how Biostar may not have sent me a "new" one and instead a refurbished motherboard. Anyway, I came back home and, of course, the reboots continued. Then, as I'm writing this post, all that keeps happening is the computer keeps freezing and the screen turns random colors every time it happens. One time it will be pink with white horizontal lines, another blue with black lines. It's weird. I don't know what is wrong and I don't want to act (RMA, technician fix, etc.) until I know the exact issue. I hope we can get to a conclusion in this thread. Thanks for sticking through my whole story
